External Thread Straight Hose Connector — Plastic Tube Fitting M6 to M14 (4mm–14mm)

Match the connector's tube size (4mm–14mm) to your hose or tube outer diameter. For thread size, match the M-designation (M6, M8, M10, M12, M14) to the female port on your fitting or manifold. When in doubt, measure the port thread diameter with a caliper — M6 is typically 6mm thread OD, M8 is 8mm, and so on. If you're replacing an existing fitting, check the markings on the old part or measure the thread pitch with a thread gauge.

Plastic straight tube connectors are generally rated for low-to-medium pressure applications, typically up to 0.5–1.0 MPa (73–145 psi) depending on tube size and fluid type. For high-pressure or high-temperature environments, contact us to confirm suitability before ordering.

These plastic connectors are generally moisture-resistant and suitable for light outdoor or damp-area use, such as garden irrigation systems. However, prolonged UV exposure or full submersion may degrade the material over time. For fully outdoor or submerged installations, consider adding a UV-resistant sealant or contact us to confirm material compatibility.

These connectors use metric external threads (M6, M8, M10, M12, M14) following the ISO metric thread standard. They are generally compatible with standard metric female ports and fittings. If your system uses NPT (National Pipe Thread) or BSP (British Standard Pipe) threads, these connectors are not a direct fit — please contact us to confirm compatibility or discuss adapter options.

For a single repair or prototype build, the 1 Pcs option is the most practical. For small projects or keeping a few spares on hand, 5–10 Pcs is a solid choice. For larger installations or workshop stock, the 20–50 Pcs packs offer better per-unit value. All quantities ship from our US warehouse.

These straight connectors are generally compatible with flexible plastic tubing, polyurethane (PU) hose, nylon tubing, and similar soft-wall tubes in the corresponding outer diameter. They are not typically designed for rigid metal pipe or high-pressure hydraulic hose. Always verify the tube OD matches the connector's listed size before installation.

In most cases, plastic straight connectors can be carefully removed and reused if the threads and barb are undamaged. Inspect the threads and sealing surfaces before reinstalling. If any deformation, cracking, or thread stripping is visible, replace the connector to avoid leaks in your hose pipe connection.
